3 3 STEREOLITHOGRAPHY-TYPE THREE-DIMENSIONAL PRINTING MATERIAL USED FOR PREPARING DENTAL THREE-DIMENSIONAL FORMED ARTICLE

摘要

In the present invention, the total manufacturing time required from molding to final curing using a 3D printer is short, and the work efficiency is excellent, and the dimensional accuracy of the dental three-dimensional sculpture is suppressed over time. Provide printing materials. A dental stereoscopic three-dimensional printing material, containing at least one type of monofunctional acrylate monomer (a) having an aromatic ring and a photopolymerization initiator (b), and containing a monofunctional acrylate monomer (a) having an aromatic ring. In all of the constituent atoms, the electronegativity difference between adjacent atoms by a covalent bond is set to be less than 1.0.
